question about inflection/derivation

[Franca Ferrari]

Dear All,

My name is Franca and I am a Ph.D student at NYU. I would like to know if
there exist some languages that have  a stem that can be followed by two or
more inflectional morphemes that are followed by a derivational marker.


ex : 'stem+INFLECT+INFLECT+DERIVATION'

I know that in Breton and in Dutch the combinations
'stem+INFLECT+DERIVATION' is attested, but I never recall any case such as
the one above.

Could someone help me by indicating me some data or his/her thought about
it? Thank you, franca
